Unfragile

cscope is a named tool, and no candidate's source page describes it, so none can be recommended as cscope itself. The closest fit among the candidates is Joern 6, a code analysis shell for finding attack surface and vulnerability variants in C/C++ source, and Octocode 7, which offers code search and navigation over local codebases. Pygments 1 is a syntax highlighter and is not a code-navigation tool, so it is a weak match.

A question back: Did you mean the cscope C source code browser, and do you need its symbol cross-referencing for C code specifically?

For agents: the 10 actions behind this answer

highlighting · Pygments verified and signed
CMake · cmake verified and signed
cffi · cairocffi verified and signed
semgrep · semgrep verified and signed
Semgrep catches security vulnerabilities in real-time and guides Claude to write secure code from the start.
parser · Protego verified and signed
· Joern website read, tools not yet checked
· Octocode website read, tools not yet checked
Octocode is evidence-first code research for AI agents. 13 research tools give Cursor, Claude, and VS Code deep access to GitHub and local codebases — code search, AST and LSP navigation, PR history, package lookup, and OQL. The same tools run over MCP or the npx octocode CLI.
wordpress-router · wordpress-router verified and signed
Use when the user asks about WordPress codebases (plugins, themes, block themes, Gutenberg blocks, WP core checkouts) and you need to quickly classify the repo and route to the correct workflow/skill (blocks, theme.json, REST API, WP-CLI, performance, security, testing, release packaging).
browser · WebDriver Support verified and signed
safe-browser · safe-browser verified and signed
Build local constrained-browser agents with a safe_browser tool that owns CDP, enforces a domain allowlist with Fetch interception, and lets a runtime Claude Agent SDK agent complete browsing tasks without raw browser, shell, or CDP access. Use when the user wants an agent to browse or scrape while

Labels are the instruments' verdict and are never changed by ranking. Agents and robots get this same answer as JSON at /api/v1/find?q=…&answer=1 and through the MCP server.
